Update.
2000-03-23  Bruno Haible  <haible@clisp.cons.org>

	* iconv/gconv_int.h (__gconv_transform_ucs2little_internal,
	__gconv_transform_internal_ucs2little): Remove declarations.
	* iconv/gconv_simple.c (__gconv_transform_ucs2_internal,
	__gconv_transform_internal_ucs2): Never	need to bswap_16.
	(__gconv_transform_ucs2reverse_internal,
	__gconv_transform_internal_ucs2reverse): Always need to bswap_16.
